<br />\ <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR GARFIELD <br /> <br />COUNTY, COLORADO, UNDER THE NATIONAL FLOOD INSURANCE PROGRAM <br /> <br />On January 3, 1986, the Federal Emergency Management Agency (FEMA) <br /> <br />identified Special Flood Hazard Areas in Garfield County, Colorado, through <br /> <br />issuance of a Flood Insurance Rate Map (FIRM). <br /> <br />The Mitigation Directorate has determined that modification of the <br /> <br />elevations of the flood having a l-percent chance of occurrence in any given <br /> <br />year (base flood) for certain locations in Garfield County is appropriate. <br /> <br />The modified base (lOO-year) flood elevations (BFEs) revise the FEMA FIRM for <br /> <br />the community. <br /> <br />The changes are being made pursuant to Section 206 of the Flood Disaster <br /> <br />Protection Act of 1973 (Public Law 93-234) and are in accordance with the <br /> <br />National Flood Insurance Act of 1968, as amended (Title XIII of the Housing <br /> <br />and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C. 4001-4128, <br /> <br />and 44 CFR Part 65. <br /> <br />A hydraulic analysis was performed to incorporate additional topographic <br /> <br />information and has resulted in a revised delineation of the regulatory <br /> <br />floodway and increased BFEs from effective Sections BA to BC, <br /> <br />The tabl e <br /> <br />below indicates the modified BFEs for several locations along the affected <br /> <br />length of the Roaring Fork River. <br /> <br />Location <br /> <br />Exi sting BFE <br />(feet )<, <br /> <br />Modified BFE <br />(feet)* <br /> <br />Approximately 2,000 feet upstream of <br />the confluence of Cattle Creek <br />Approximately 3,000 feet upstream of <br />the confluence of Cattle Creek <br /> <br />5,945 <br /> <br />5,945 <br /> <br />5,948 <br /> <br />5,949 <br />
